A simple approach is better in that case. However, there is nothing that prevents you from using more accurate formula, except that you will have to recompute coefficients on every external change of position, speed or gravity. | |
| Jun 1, 2019 at 20:17 | comment | added | DMGregory♦ | What you're describing in steps 1 & 2 is called (symplectic) Euler integration. It's popular to show in tutorials because it's simple, easy to understand, and easy to build upon (even a reader who's unfamiliar with calculus can reasonably guess at how they'd add a new physics influence into either the velocity or position step). It's not the only tool in use in shipped game systems though. | |
